Smell of gas coming out of exhaust....running rich
If the vehicle is still running original systems then you would need to take it to someone with 1 of the hand programmers to readjust the fuel system settings. If this vehicle has been converted over to or originally was a carborated There are typically 2-4 mixture screws depending on the unit. They will be infront of and behind the carborator. To adjust a carborated you will typically take a flat head screw driver and turn all the way to the right till they are only "finger tight" Once there, note a starting point and from there VIA each screws individual starting point. Turn them all 1 1/2 turns, this will place the carborator at the factory starting position. From there you can then start the vehicle and while it's idleing you can begin to adjust all mixture screws by turning 1/2 a turn till the vehicle looks, sounds, and smells like it is running correctly.
Another method I have seen is using a vaccume pump to register preasure, there are some video's out there to do this method and it can help you fine tune it a little more then one can just by ear. I hope this has helped you or atleast set you in a direction to getting the issue solved.
